Abstract

L'invention concerne un élément d'ancrage conçu pour une installation hydraulique. Cet élément d'ancrage comprend au moins une masse de lestage destinée à l'alourdir et est caractérisé en ce qu'il présente plusieurs éléments de protection anti-cisaillement agencés de manière à pouvoir se déplacer sur des guidages latéraux dans l'élément d'ancrage, de sorte que, lors de la mise en place de l'élément d'ancrage au fond de l'eau, les éléments de protection anti-cisaillement venant en contact avec le fond de l'eau exercent une pression sur celui-ci en raison de leur poids propre et se déplacent individuellement le long du guidage latéral respectif, jusqu'à ce que l'élément d'ancrage trouve une position d'équilibre.
